Improvement in harness-operating mechanism for looms



UNITED STATES PATENT CFFICE.

JOHN F. GEBHART, OF NEW ALBANY, INDIANA.

IMPROVEMENT IN HARNESS-OPERATING MECHANISM FOR LOOMS.

Specication forming part of Letters Patent No. 91,431q dated June 15, 1869.

To all whom fit may concern:

Be it known that I, JOHN F. GEBHART, of New Albany, in the county of Floyd, and in the State of Indiana, have invented an Improvement in Operating Heddle-Frames or Shed-Motion in Looms; and do hereby declare that the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention is intended as an improvement upon my patent for a loom, No. 66,828, bearing date July 16,1867; and consists in the combination and arrangement of mechanism, in a simplified manner, for giving motion tio the heddle-frames, as will be hereinafter set orth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this speciication, and in which- Figure l is a side elevation; Fig. 2, an end elevation. Fig. 3 is a side view of a cam with its angular lever; and Fig. 4 is an edge view of the same.

A represents the frame of a loom, at one end of which is a standard, B, of suitable height. At the top of this standard is a series of cams, c c, mounted on a common shaft, D, which, at one end, is provided with a miter-Wheel, E. Motion is communicated to this shaft D and its cams c c by means of a horizontal crankshaft, F, having its bearings in the ends of the frame A, said shaft being provided with a miter-wheel, F', which gears into a miterwheel, G, at the lower end of a vertical shaft, H, this latter shaft having at its upper end another miter-wheel, I, which gears into the wheel E, above mentioned.

On another shaft, at the upper end of the standard B, is mounted a series of L-shaped levers, J J, provided with lugs a a, the shape of which is seen in the enlarged view in Fig. 3. The extremities of the levers J J are, by means of ropes or strings, connected with the top and bottom of the heddle-frames K K, said strings passing over and around rollers placed above and below the machine, as seen in Fig. 1, for that purpose.

The advantages of this arrangement are its simple and easy application to looms. The parts that are most likely to Wear out are el vated above the place where the dust and dirt fall, as well as being convenient to clean and oil. In regulating the heddle-frames a person is not required to get under the loom. The whole lower part of the loom is left clear for attaching shuttle-boxes or other motions, and renders the operation of changing from one twill to another very easy. The loom weaves the goods face side up, enabling weavers to easily detect broken threads.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the eccentric cams C O and levers J J, constructed and arranged as described, and mounted upon one end of the main frame A and above the heddle-frames K, so as to free the same from the falling dirt and dust, substantially as set forth.

2. The combination of t-he crossshaft F with miter-Wheel F, vertical shaft H, with wheels Gr I, stand B, cross-shaft D, with wheels E, cams C, levers J, and frames K, all constructed and arranged upon the frame A with its pulleys, and operating substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of March, 1869.

JOHN F. GEBHART.
